How to Protect Your phpBB Forum From Spam Bots
February 23, 2007 by Gaman
While forum spamming either caused by bots or humans are not a security threat, it’s still very much a nuisance to the forum admin.
I have several phpBB forums which have running for a couple of years now and they were like magnets to spammers especially spam bots.
Deleting these spam bots manually was tiring and time wasting.
At some point, I turned off automatic registration completely and requested potential members to write to me manually if they want to join the forum. This of course presented another hurdle to users and had decreased the registration rate.
You can enable the built-in Visual Confirmation during registration but this measure can be easily defeated even by the simplest spam bots.
Then I searched for a MOD that I can install and came across Textual Confirmation by olpa.
Textual Confirmation (TC) works by asking potential member a question during the registration process. This question is selected at random from a collection of questions you’ve created beforehand in the Administration Panel so you can essential ask anything.
If the user gives the wrong answer, TC rejects the registration. You and the community spam database will be notified if this happens.
Yes TC can still be cracked but so far it works like a charm on my forums. I can leave them unmonitored for days (especially when I were preoccupied with other stuff) and come back to see not a single spam posting of Britney Spears naked pictures among others.
If you have phpBB forum and tired of spam bots, I recommend you to install TC to combat the problem.
